SB
Summary:
Execution in investing refers to the completion of a buy or sell order for a security. It is a critical aspect of the trading process, as it determines when and at what price the order gets filled. This article explores the various methods of execution, that is executing trade, the role of brokers, and the concept of best execution mandated by regulatory bodies like the Securities and Exchange Commission (SEC).

Understanding execution in investing
Execution in the world of investing involves the completion of a buy or sell order for a security, such as stocks, bonds, or other financial instruments. It’s crucial to note that execution happens when an order is filled, not when the investor initially places it. When an investor submits a trade, it is sent to a broker, who then determines the best way to execute it.
Methods of executing trades
There are several methods for executing trades, and they encompass both manual and automated processes. Let’s explore some of the common methods:
- Order to the floor: This method involves human traders processing the transaction, which can be time-consuming.
- Order to market maker: On exchanges like the Nasdaq, market makers provide liquidity, and the investor’s broker may direct the trade to one of these market makers for execution.
- Electronic communications network (ECN): An efficient method where computer systems electronically match buy and sell orders.
- Internalization: Brokers may execute the order in-house if they hold an inventory of the stock in question.
Best execution and broker obligations
Brokers are legally obligated to provide investors with the best possible order execution. The Securities and Exchange Commission (SEC) mandates this requirement and also necessitates brokers to report the quality of executions on a stock-by-stock basis. This includes how market orders are executed and how the execution price compares to the public quote’s effective spreads.
Despite these regulations, there is an ongoing debate regarding whether brokers always route orders for best execution or if they have other motivations, such as generating additional revenue streams.
The impact of execution on trading costs
The cost of executing trades has seen significant reductions due to the growth of online brokers. Many online brokers offer commission rebates to customers who execute a certain volume of trades or dollar value per month. This is especially relevant for short-term traders who need to keep execution costs as low as possible.
If an order is a market order or can quickly convert into one, the chances of settling at the desired price are high. However, in the case of a large order broken down into several smaller orders, it may be challenging to execute at the best possible price range. This introduces an execution risk, referring to the lag between order placement and settlement.
Execution and dark pools
Dark pools are private exchanges or forums designed to help institutional investors execute large orders without disclosing their quantity. They offer advantages such as increased privacy and the potential for better execution prices compared to public exchanges. When institutional traders place sizable orders on public exchanges, their visibility can impact the stock’s price. Dark pools can help mitigate this issue by executing at the mid-point of the bid and ask price.
It’s important to note that dark pools have been a subject of skepticism among retail investors due to their lack of transparency and limited access.
Example of execution
Let’s consider an example to better understand execution.
Olga enters an order to sell 500 shares of stock ABC for $25. Her broker is obligated to find the best possible execution price for the stock. After investigating the stock’s prices across markets, the broker determines that they can execute the order internally at $25.50, compared to the $25.25 price at which it is trading in the markets. This decision results in a profit of $125 for Olga.
Execution Timing and Impact
When it comes to execution in investing, timing is crucial. Depending on when you place your order, the execution price can vary. For example, if you place a market order to buy a popular stock during the opening minutes of the trading day, you might experience a difference in execution price compared to placing the same order later in the day. This phenomenon is often referred to as the “opening price volatility.”
Let’s take an example:
Imagine you want to buy 100 shares of Company X, which is trading at $50 per share. You place a market order at the market open. Due to the higher demand during this time, your order gets executed at $51 per share, costing you an extra $100. Now, if you had placed the same order later in the day, when the stock stabilizes, you might get a more favorable execution at the original $50 per share.
Slippage and Its Impact
Slippage is another critical aspect of execution in investing. It refers to the difference between the expected execution price and the actual execution price. Slippage can occur due to various factors, including market volatility, order size, and the speed of order execution.
Here’s an example:
Suppose you place a limit order to buy 1,000 shares of a stock at $25 per share. However, the market experiences a sudden surge in trading activity, and your order is executed at $25.50 per share. This 50 cents difference per share results in an additional cost of $500 for your trade. Slippage can have a significant impact on your overall trading costs, especially for large orders in volatile markets.
Algorithmic Trading and Execution
Algorithmic trading, also known as algo trading, has become increasingly popular in the world of finance. It involves the use of computer programs to automate the execution of trading strategies. Algo trading can optimize execution by taking advantage of market inefficiencies and swiftly reacting to changing conditions.
Let’s consider an example of algo trading:
An investment firm utilizes an algorithm to execute a trading strategy that aims to profit from small price discrepancies between two related stocks. The algorithm constantly monitors the price of Stock A and Stock B. When it detects a price difference that exceeds a certain threshold, it automatically executes a pair trade—buying one stock and selling the other to take advantage of the price convergence. This automated approach allows the firm to capture profits quickly and efficiently.
Conclusion
Execution is a fundamental aspect of investing that determines when and at what price a buy or sell order is filled. Brokers are legally required to provide investors with the best possible order execution, and regulatory bodies like the SEC monitor and enforce these obligations. The impact of execution on trading costs can be significant, making it essential for traders to understand the various execution methods and their implications. Dark pools offer an alternative execution venue for institutional investors seeking improved privacy and execution prices. Whether you are an experienced trader or a newcomer to the world of investing, grasping the intricacies of execution is crucial for making informed decisions and managing trading costs.
Frequently asked questions

Execution timing is influenced by several factors, including market volatility, order size, and the type of security being traded. Traders should consider these factors to make informed decisions about when to execute their orders for optimal results.
How can traders effectively manage slippage during execution?
Slippage can impact the execution price of a trade. To manage slippage effectively, traders can employ strategies such as using limit orders, setting price boundaries, and staying updated on market conditions. These practices can help mitigate the impact of unexpected price movements.
What are the advantages of algorithmic trading in execution?
Algorithmic trading can enhance execution efficiency by automating trade decisions. It offers benefits such as quick execution, reduced emotional trading, and the ability to respond to changing market conditions.
